MUSIC TYPE-WRITER.

SPECIFICATION forming part of Letters Patent No. 650,447, dated. May 29,1900. Application filed June 5, 1899. Serial No. 719,344. (No model.)

ToaZZ whom, it may concern.-

Be it known that I, FRANK H. BEALs, a citizen of the United States,residing at Worcester, in the county of W'orcester and State ofMassachusetts, have invented a new and useful Music Type-Writer, ofwhich the following is a specification.

My invention relates to a machine which has been especially adapted forprinting music.

The object of my present invention is to provide a strong, compact,efficient, and inexpensive typc-writing machine, and while a machineembodying my invention is especially adapted for printing music certainnovel features thereof may be employed with advantage in other classesof type-writin g machines.

To these ends myinvention consists of the parts and combinations ofparts, as hereinafter described, and more particularly pointed out inthe claims at the end of this specification.

In the accompanying ten sheets of draw- 2 5 ings, Figure l is a planview of a type-writing machine constructed according to my invention.Fig. 2 is a front view thereof. Fig. 3 is a side view thereof. Fig. 4 isa rear view thereof, partly broken away. Fig. 5 is an en- 0 larged planview of a portion of the type-bars and key-levers which constitute themain printing mechanisnn Fig. 6 is an enlarged central transversesectional view of a portion of the machine. Fig. 7 is a partial frontview of the paper-carriage. Fig. Sis a transverse sectional view of thepaper-carriage, taken on the line 8 8 of Fig. 7. Fig. 9 is a detail viewillustrating the spacing mechanism and the ribbon-feeding connections. aFig. 10 is an enlarged transverse sectional view taken on the line 10 10of Fig. 9, illustrating the connections employed for raising thesecondary pa per-carriage. Fig. 11 is asectional View illustrating thecarriage-feeding pawl'on an enlarged scale. Fig. 12 is a plan view,partially broken away, illustrating the connections employed for feedingthe carriage. Fig. 13 is a rear View, partially broken away, of thecarriage'which constitutes the secondary printing mechanism. Fig. 14 isa plan view of the same, partially broken away. Fig. 15 is a sec-'tional View taken on the line 15 15 of Fig. 13. Figs. 16 and 17 aredetail sectional views illustrating the ruling attachments which may beemployed and are taken on the lines 16 16 and 17 17 of Fig. 14,respectively; and Fig. 18

is a fragmentary view of one of the combs in which the type-barsaremounted and guided.

In printing musical compositions a large number of characters aresometimes employed. Many of these characters-for example, thoseindicating repeats, retards, time, &c.may be employed comparativelyrarely in any one musical composition, while characters indicating notesor rests of various lengths are repeated and employed with' frequency.

If each of the characters employed in printing music'should be given aseparate typebar and key-lever, the printing mechanism or type-basket ofa music type-writing machine would necessarily be extremely large. Onthe other hand, it is desirable that a machine for printing music shouldbe capacitated to print all characters desired and nothing should beleft to be lettered or filled in by hand.

One of the especial objects of my present invention is therefore toprovide a compact and simple machine having a comparativelysmallkeyboard and type-basket for printing the ordinary orfrequently-employed characters and with a supplemental or secondaryprinting mechanism for printing those characters more rarelyemployed-that is to say, a type-writing machine constructed according tomy invention preferably employs a main printing mechanism for printingthe ordinary or frequently-employed characters and a norwally-inactivesupplemental printing mecho anism arranged to be brought into operationto print the unusual or more rarely employed characters. In addition tothis especial fea ture of novelty a type-writing machine constructedaccording to myinvention comprises a specially-constructedpaper-carriage having connections for producing an advance or feedingmovement and for raising and lowering the same and with novelribbon-feeding connections, as will be hereinafter more par- :00ticularly pointed out.

- Referring to the drawings and indetail, a

'may be carried by legs or supports 21.

type-writing machine constructed according to my invention, as hereinillustrated, comprises a machine frame or casing 20, which The rear sideof the casing is preferably closed by a hinged section or cover 22, andjourn aled inside the frame is a supply-roll 23, from which a supply orsheet of paper for the machine may be torn ed, as desired.

The main printing mechanism of the machine preferably comprisestype-bars 24,

which are journaled in racks or combs to strike at a common center orprinting-point.

A series of key-levers 26 are journaled in combs near the front of themachine, and each key-lever is provided with a pin 27, extending downthrougha slot in the frame of the machine and having a spring 28 coiledthereon to hold said key-levers up in their normal position. The rearends of the key-levers ex.- tend under and engage the type-bars, so thatwhenevera key-lever is depressed its type: bar will be raised or thrownup to the printing-point in a well-understood manner, and in practice Ipreferably arrange a bufferspring 29, as shown most clearly in Fig. 6,in position to cooperate with each of the typebars 24 to insure a promptreturn of each typebar to its normal position after the same has beenoperated. isin as thus constituted is preferably capacitated to printthose characters which occur most frequently in musical compositions,while a supplemental or distinct printing mechanism is employed forprinting the more rarely used characters. This supplemental printingmechanism may be arranged as follows: Extending up from the frame 20 ofthe machine are posts 30, carrying tracks or ways 31. Mounted on thetracks or ways 31 and adapted to be secured in its normal positionthereon by means of set-screws 33 is a frame or carriage 32. The frameor carriage 32, as illustrated most clearly in Figs. 13 to 17, isprovided with a central aperture or opening 36, which is normallyarranged opposite the printing-point of the main printing mechanism.Movably mounted in the carriage 32 at each side of the opening 36therein is a series of plungers 34, each plunger 34 being normally heldin a retracted position by a spring 35. The plungers 34 at their rearends are provided with those types or characters which are but seldomemployed in musical composition's.

In order to print or take the impression of a character carried by oneof the plungers 34, I preferably employ a hammer controlled from thekeyboard of the machine.

,'AS illustrated most clearly in Fig. 0, 39 designates a hammer, whichmay be of substantially the same construction as one of the type-bars ofthe main printing mechanism, and arranged to operate the hammer 39 is acentral key-lever 40, as shown most clearly in Fig. 1. As also mostclearly shown in Fig.

1,the upper track '31 is preferably graduated The main printing mechanorprovided with an index, and cooperating with the index on the track 31is a pointer 37, extending up from the carriage 32. The pointer 37 whenthe carriage is in its normal position will serve to indicate to theoperator the middle or printing point, and in practice the pointer 37 ismade to perform still another function by being extended up high enoughto serve as a guide for setting or adjusting the machine when music isbeing copiedthat is to say, when a bar of music is to be duplicated byfollowing the copy with the pointer the proper keys may then be struckto produce the desired copy.

In order to employ the supplemental printing mechanism to print acharacter, the set screws 33 are first loosened, and the carriage isthen moved to bring its pointer 37 opposite the desired character on theindex on the track 31, and by then operating the central key-lever andhammer an impression of the desired character will be made at theprinting-point of the machine. The carriage 32 is also preferablyprovided with an ink-ribbon 43, which is employed both in connectionwith the main printing mechanism of the machine and the supplementalprinting devices thereof. The ribbon and its operating connections maybe mounted in the carriage 32 in any desired manner.

As illustrated in Figs. 13 and 14, the carriage 32 is provided near itsends with movable casings 41, which may be moved into and out ofposition by finger-pieces 42. Removably journaled in the casings 41 arethe ribbon-spools 44, one of said ribbon-spools being geared to feed orwind up the ribbon by means of connections hereinafter described. At theextreme ends of the carriage 32, outside of the ribbon-spools, Ipreferably employ ruling or marking wheels for ruling the straight lineswhich constitute the staff on which the music may be written and forruling the vertical lines for dividing the music into measures or forruling lines which may be inclined at different relative angles.

The ruling device for ruling the lines which form the staff on which themusic is to be written comprises a casing 45, which may be moved orcontrolled by a key 46. Journaled in the casing 45 is a ruling-wheel 47,which is supplied with ink from an ink-roll 48. At the opposite end ofthe carriage 32 is a casing 49, having a ruling-wheel 51 journaledtherein, which is supplied with ink from an ink-roll 52. Tlie'casing 49is controlled by a finger-key 50 and may not only be pushed in to bringits ruling-wheel 51 into contact with the paper, but it may also beturned to bring the ruling-wheel to any desired inclination for rulingoblique or inclined lines.

Extending up from the rear part of the frame of the machine are posts53, carrying a track 54:. Mounted to run on the track 5i and in ways inthe frame of the machine is a main paper-carriage 55. (Most clearlyillustrated in Figs. 7 and 8.) The main papercarriage 55 consists,essentially, of arectangular frame having arched or slotted end pieces,which may straddle the track which supports the secondarypaper-carriage. Mountedin the main paper-carriage 55 is the secondarypapercarriage 56. The secondary paper-carriage 56 consists, essentially,of a rectangular plate of hard rubber or other-material, over which thepaper is stretched and forms a platen to support the paper while thesame is being printed upon. The secondary carriage 56 rests upon and issupported by a track 57, as shown most clearly in Fig. 9. The track 57is carried by links 58 and may be raised and lowered by connections fromthe keyboard of the machine. The connections for raising and loweringthe track 57 are most clearly illustrated in Fig. 10. As shown in thisfigure, the track 57 rests upon and is supported by a roll 59, carriedby a vertically movable rack 60. Meshing with the rack 60 is a pinion61, secured on a shaft 62. On the opposite end of the shaft 62, as shownmost clearly in Fig 12,, is a gear 63, which meshes with and may bedriven by a sector 64. Extending from the sector G l is a link 65, whichis connected to the lower end of an elevating-lever 66, as shown mostclearlyin Fig. 3. The elevatinglever 66 is provided with a pointercooperating with an index-plate on the frame of the machine, as shownmost clearly in Fig. 1, so that by shifting the elevating-lever 66 thepaper-carriage may be raised and lowered and the desired character maybe printed on any line of the staff desired.

The paper clamping and feeding devices may be of any of the usual orordinary constructions. As herein illustrated, the secondarypaper-carriage 56 is provided with a paper table or guide for directinga sheet of paper from the back side of the machine to the front of afeed-roll 68. Cooperating with the feed-roll 68 is a spring-pressedpaperclamp 69, which may be turned back when desired by a finger-piece70, as shown in Fig. 71. From the paper-clamp (59 the paper may bepassed up under a paper-roll 7i, and the upper end of the paper may beturned back over a wire supportingframe 72, carried by the posts 53.

The paper may be spaced for successive lines of music by means of thefeed-rolls G8 and 71, and between these rolls it may be stretchedtightly over the surface of the hardrubber plate which forms the platen,so that the same will lie smoothly thereover to receive the impressionfrom .the type bars or characters mounted in the supplemental printingmechanism.

- In order to hold the lower end of the sheet which is being. printedout of the way, if desired, the lower end of the sheet may be turned upand held in place bya frame formed by wires 73.

The connections for feeding the carriage in order to produce thenecessary spaces between successive characters and for feedingtheink-ribbon are most clearly illustrated in Figs. 7 to 11, inclusive.Asshown in these figures, the main paper-carriage 55 is provided with aratchet-toothed spacing-rack 74 and with a ribbon-feed rack 91. Meshingwith and arranged to operate the spacing-rack As illustrated in Fig. 12,the spacing-lever 78 has a pin-and-slot connection with a lever 79,

which extends to one side of the machine. The lever 79 is connected to'aspacing-key 80, and connected to the spacing-key 80 by means of apin-and-slot connection is'a secondary spacing-key 81. The motion of thesecondary spacing-key 81 is limited by a stop or pin 82. By means ofthis construction it will be seen that when the spacing-key 81 isoperated a comparatively-small motion will be imparted to thespacing-lever 78; but when the spacing-key 80 is operated the motion maybe continued, by reason of the pin-and-slotconnection with thespacing-key 81, even after said spacing-key 81 has engaged its stop 82,so as to impart a somewhat-greater motion to the spacing-lever 78, andhence secure asome what-greater motion or advance of the papercarriage.

In addition to the two spacing-keys 80 and i 81 I preferably employaspacing-key 98,which may be located at the front of the keyboard in theordinary position.

To operate the spacing-lever 78 from the space-key 98, I preferablyemploy a lever 83, having a pin-and-slot connection with thespacing-lever 78 at its rear end and connected at its front end to anarm 84, extending down from one of the links 85, which support thespace-key 98.

The space-key 98 is normally held up by means of a spring 86, so that bydepressing said space-key the lever 83 will be turned, and through itspiu-and-slot connection it will turn the spacing-lever 78 to feed oradvance the paper-carriage.

The distance or amount of feed secured by the spacing-key at the frontof the keyboard may of course be equal to orgreater than that secured byeither one of the space-keys at the side of the machine, and, as shownmost clearly in Fig. 12, the spacing-lever 78 is preferably slotted, sothat when it is operated by means of the space-key at the front of thekeyboard the lever 79, connected to the spacekeys at the side of themachine, will not be affected. The ribbon-feeding and carriage-releaseconnections are most clearly illustrated in Figs. 9 and 15. As shownmost clearly in Fig. 15, the shaft of one of the ribbon-spools isprovided with a gear 87, which meshes with and is driven by a gear 88,secured on the upper end of a vertically-movable shaft 89. Also securedon the shaft 89 is a gear 90, which meshes with and is driven by theribbon-feed rack 91, carried by the paper-carriage. By. means of thisconstruction when the carriage is advanced the ribbon will be wound fromone ribbon-spool onto the other, and in order to permit thepaper-carriage to be moved back to its initial position I preferablyprovide connections for releasing the ribbon-feed and the spacing-pawl.

As illustrated, 92 is a releasing-key, which may be pushed down to movedown the vertically-movable shaft 89, so as to throw the gears 87 and 88out of mesh with each other to permit the paper-carriage to be movedback without affecting the ribbon-spools. Extending down from therelease-key 92, as most clearly shown in Fig. 9, is a rod 94, which isconnected at its lower end to a lever 95. The

lever 95 connects with and operates a lever- 96, which is connected by alink 97 to pull down the feed-pawl 75, so that by depressing therelease-key the carriage may be freed both from its spacing connectionsand from the ribbon-feeding connections, so that the same will be freeto be moved back to its initial position, as desired.

To indicate the approaching completion of a line, the machine may beprovided with a bell 98, which may be sounded by a spring striker 99,operated by a catch or pawl 100 on the carriage, as shown most clearlyin Fig. 12.

By means of this construction it will be seen that I have provided amachine which may be of a comparatively-compact, simple, and inexpensiveconstruction, which at the same time will be capacitated to print agreat variety of diflerent characters in any desired sequence orrelation to each other.

The operation of the several devices constituting a type-writing machineconstructed according to my invention have been so fully explained indescribing the construction thereof that a description of the operationof the machine as a whole is not believed to be necessary.

I am aware that numerous changes may be made in the construction of mytype-writing machine by those skilled in the art and that certainfeatures of my machine may be applied to diiferent classes ofconstructions from that herein shown and described. I do not wish,therefore, to be limited to the construction herein shown and described;but
